Researchers at Amsterdam UMC have overturned an important assumption in the field of biological pacemakers. New preclinical studies show that the transcription factor TBX18 does not produce true biological pacemaker activity, but the ion channel Hcn2 produces potent pacemaker function in the heart. Rethinking TBX18 Based on widely cited and influential papers, TBX18 has been reported for more than a decade to reprogram active ventricular cardiomyocytes into sinoatrial node-like pacemaker cells. A team at Amsterdam UMC systematically revisited this claim using a low-immunogenic adeno-associated virus (AAV) vector and detailed electrophysiology. They showed for the first time that conventional high levels…

A major PFAS class action lawsuit against chemical manufacturer 3M has been filed in Victoria’s Supreme Court, and the ABC understands the case involves hundreds of companies and organizations and could result in claims reaching billions of dollars.The class action was first filed in Victoria’s Supreme Court in late 2024, but documents outlining the case were only recently released to the ABC.In these documents, plaintiffs’ lawyers say they believe this is Australia’s first class action lawsuit brought against 3M over products containing PFAS.Because this class action lawsuit is so large, ABC understands that the total amount of damages sought could…

A dangerous tapeworm that has spread across North America has been discovered in the Pacific Northwest, according to a new study. Scientists have discovered a parasite known as. Echinococcus multilocularisa local coyote, and the first time it has been confirmed in a wild host along the contiguous U.S. West Coast. This parasite typically infects coyotes, foxes, and other canids. These animals often show no signs of illness, but tapeworm transmission can cause serious illness in domestic dogs and humans. For decades, E. multilocularis It is recognized as a major public health concern in Europe and some parts of Asia. However,…

Chronic wasting disease (CWD) is commonly associated with animals. But a new study by researchers at the University of Calgary and international collaborators investigated the possibility that CWD can spread from deer, elk and other cervids (ungulates that eat plants) to other species. There have never been any confirmed cases of CWD in humans. But researchers say the findings support the need for continued surveillance and research as the disease spreads geographically. CWD, a deadly neurological disease caused by infectious proteins known as prions, continues to spread across North America, including growing regions of Alberta. In a newly published study,…

In an unusual move, the nonprofit organization Blood Cancer United announced Thursday that it will purchase the remaining supply of the discontinued investigational cancer drug Luberta. As part of the deal, Blood Cancer United, formerly known as the Leukemia and Lymphoma Society, will also receive Investigational New Drug designation, manage a compassionate use program for children with rare forms of blood cancer, and distribute the drug free to patients while supplies last. Luberta (rubertamab tazevibulin) is an antibody-drug conjugate that targets the folate receptor (FOLR1) and was originally developed to target lung and ovarian tumors in adults, but it serves…

According to a new report from the Bipartisan Policy Center (BPC), use cases for artificial intelligence across federal health agencies will skyrocket from 2024 to 2025, led by the Food and Drug Administration (FDA), which saw a 148% year-over-year increase. Within the Department of Health and Human Services (HHS), AI use cases increased by 87% at the Centers for Disease Control and Prevention (CDC) and by 78% at the Centers for Medicare and Medicaid Services (CMS). The National Institutes of Health (NIH) saw a 51% increase. BPC researchers analyzed the HHS Artificial Intelligence Use Case Inventory and compiled the report.…

During the first five years of life, more than half of the calories consumed by a growing child are used to fuel massive construction projects inside the skull. Building the brain (all the neural connections that form memories, store language, perceive the world, and control bodily movements) is a unique, energy-intensive creative act. The unique structure of a child’s mind, which defines how he or she thinks and feels, is constantly being shaped by the interaction of the environment and the genetic blueprint enmeshed within the developing organization. Scientists have long wondered which aspects of childhood most influence neurodevelopment. However,…

For thousands of years, bison roamed the Great Plains of North America and were an essential resource for indigenous hunters. These hunting traditions continued until the late 1800s, when overhunting brought the bison population to the brink of extinction. But long before its collapse, hunters relied on a variety of strategies and locations to capture bison, sometimes moving from one location to another. A new study investigated why hunters stopped using a particular site in central Montana known as the Bergstrom Site. Bison were abundant in the area, but the site was used intermittently for about 700 years before it…

People with traits such as narcissism and psychopathy exhibit both common and distinct physical differences in brain regions associated with empathy and social cognition. These anatomical variations suggest that while unpleasant personality traits share biological roots, they also have unique features within the human brain. This research Neurotransmission Journal. Psychologists often group certain unpleasant personality traits under one banner known as the Dark Triad. This conceptual group includes Machiavellianism, subclinical narcissism, and subclinical psychopathy. Researchers have debated how best to categorize these traits because they frequently overlap in real-world behavior and interpersonal conflict. Each Dark Triad trait includes a recognized…

As cybersecurity threats have proliferated across industries in recent years, biopharmaceutical companies have emerged as prominent targets, with intellectual property, patient data, and other sensitive information at risk. Now, Novo Nordisk is the latest pharmaceutical giant to report a data breach. In an incident notification Thursday, Novo said it had recently identified a security breach affecting certain internal IT systems, adding that a “limited amount of information related to patients participating in some of our clinical trials” had been compromised. As part of its investigation, the company discovered that certain data had been “copied externally without authorization,” according to the…
